The writer recommended the aspiring runner to think of all the exercise they do in the course of their normal working life. According to him, even getting up from your desk to go to the water cooler counted for something. I did far more than that. I carried ladders and planks around. I painted ceilings while holding myself at contorted angles. I held cans of paint for minutes at a time. This was going to be a doddle. I set my alarm clock half an hour earlier than usual, and the following morning I ventured out in my new singlet, shorts and shoes. I rather wished I had bought a mask as well. I walked for five minutes. No problem. I ran hard for about a hundred yards and then the pain began, so I followed Jan's advice and stopped. I walked for a few minutes more and then started to run again. The pain began more quickly this time. My body had started to realize what was being done to it. I slowed down to a walk again and headed for home. Jan said the important thing in the early stages was to avoid causing sprains or pulled muscles by excessively ambitious exercise. I got back to the flat having achieved that without much difficulty.

'Hello? Miranda? I just wanted

I picked up the phone.

'Hi, Mum.'

'I didn't wake you, did I?'

'No. I was about to leave.'

'I just wanted to thank you for yesterday. I was going to ring last night, but then Kerry and Brendan stayed so long… It all went well, didn't it?'

'It was very nice.'

'Doesn't Kerry seem happy?'

'Yes.'

'Do you know what? I think it's a miracle.'

'Mum…'

'A miracle,' she repeated. 'When I think how,,,' I closed my eyes and the words slid into each other. I was going to be good.

'Hi Miranda. It's me, Kerry. Miranda? Are you there?' There was a silence, then a man's voice in the background, though I couldn't catch what he said. Kerry giggled, then said, 'We just wanted to say how are you, and it would be nice to meet up again sometime. What's that?… Oh, Brendan says hello from him too…' I pressed the button to erase the message.

I ran three times that week and I didn't notice any discernible difference. My lungs still hurt as soon as I jogged more than fifty paces; my legs still felt like lead and my heart a stone jolting around inside my ribcage. On hills, people often walked briskly past me. But at least I persevered, and I felt good about that.

On Friday evening, I went out to a party given by my friends Jay and Pattie. I danced and drank beer and then wine, and then some strange schnapps from Iceland that Pattie found at the back of her cupboard when most of her guests had left and we were at the lovely stage of the night, when you don't need to make an effort any more. A dozen or so of us sat around in their dimly lit living room, which was strewn with beer cans and fag ends and odd shoes, and sipped cautiously at the schnapps, which made my eyes water. There was a man I'd met, his name was Nick. He sat cross-legged on the floor in front of me, and after a bit he leaned against my knees, relaxing his weight. I could feel the sweat on his back. I waited a few minutes and then I put my hand on his hair, which was short and soft and brown, like an animal's fur. He gave a little sigh and tipped his head back so 1 could see his upside-down face. He was smiling faintly. I leaned forwards and kissed him quickly on his smile.

When I left, he asked me if I'd like to see him again.

'Yes,' I replied. 'OK.'

'I'll call you.'

'Do that.'

We looked at each other. Beginnings are so very lovely, like smashing that first small hole in the wall and glimpsing a world on the other side.

Nick did call two days later. There seems to be a strict code about when you call, the way there used to be a code about on which date to kiss for the first time. If you call on the same day, you're virtually a stalker. If you call the day after, you're maybe a bit desperate because, as the first day is out of the question, the second day is really the first day, so you're calling on the first day. If they're going to call at all, people call on the third day. If you wait longer than the third day, you might as well not call at all. The person will have either married or emigrated. Personally I've never paid any attention to the code. Life is too short. If it had been me, I would have called the moment I was home.

So Nick called and it was all pretty simple. We arranged to meet the next evening at a bar in Camden Town. I was five minutes early and he was a few minutes late. He was wearing faded jeans and a checked shirt which hung loosely under his leather jacket. He was unshaven and his eyes were very dark brown, almost black.

'You're a decorator,' he said. 'Pattie told me. And I can see some paint in your hair.'

I rubbed my hair self-consciously.

'There's nothing I can do about it,' I said. 'However much I check, there's always a spot somewhere round the back I've missed. It falls off in the end.'

When I meet people, they become improbably excited by the fact that I'm a woman doing the work I do. You'd think I was defusing bombs. Still, it gives me something to talk about. And it's a bit like being a doctor. I get asked for my advice. People ask me about how they should do up their homes.

Then Nick asked me what I wanted to do after.

'After what?' I said, pretending not to understand.

'Well. I mean – do you want to always be a decorator?'

'You mean, instead of getting a profession?'

'I guess so,' he said uncomfortably.

'Yes,' I said simply. 'This is what I want to do.'

'Sorry – that probably sounded really patronizing.'

Yes, it did, so I just asked Nick what he did. He told me that he worked for an advertising company. I asked if they'd done anything I would have seen. Lots, he said. He said that they were the ones who'd done the commercial with the fluffy talking pig. Unfortunately I hadn't seen it. I asked what he was working on now, and he replied that they'd recently won a huge account with an oil company and he was working on a report in preparation for the campaign.

But it didn't matter. What mattered were the things going on underneath the conversation, the things we weren't saying. After what seemed like a short time I looked at my watch and was surprised we'd been talking for over an hour.

'I've got to go,' I said. 'I'm having dinner with this old friend of mine. Laura,' I added, to make it clear that I wasn't off to meet a man who might be a boyfriend or an ex-boyfriend or someone I might be considering as a boyfriend.

'I'm sorry,' he said. 'I hoped that we could have dinner. Or something. Not tonight, obviously. What about, I don't know, Thursday?'

I had arranged to see Troy on Wednesday that week, so Thursday sounded fine. I walked out of the bar thinking, yes, I was sure, almost sure at least, that something was going to happen. I had another thought as well, almost a scary one: maybe this was the best bit. Probably for the next few days or weeks we would have the excitement of a new object in our lives, exploring it, finding out about it. We would ask each other questions, tell carefully edited stories from our earlier lives. We would be so nice to each other, so concerned and thoughtful and just endlessly curious. And then what? Either it would fade away or just end quickly, and we would lose touch and become a memory. Somehow it never subsided into pleasant friendship. There was no way back to that. Or we would become a couple, and even then we would have to subside into some sort of normality in which we got on with our jobs and had anniversaries and had joint opinions about things and we would complete each other's sentences. It could be good. People say so. But it could never have the sheer possibility of the beginning. I felt wistful and it seemed to suit the early evening. On one side of the road the cars and shopfronts and people walking home from work were painted in gold from the last of the sun. On the other side of the road they were lost in deep shadow.
